` Specification of Letters Patent.

Application filed March 1, 191711 eral No. 151,739,

To all whom t may concern:

Be it known that We," llenar Kirnriran endHFRANn M. KAUFMAN, citizensiofithe United States, residing` atz Philadelphia, county of Philadelphia, and Stateiof Pennsylvania, have invented certain new anduseful lhnprovenients in `Woven Pile Fabrics, of Whichthe following is a specification.

Uur invention relates to `improveinents in Woven `pile fabrics, the objectief `the invention being to provide a cut pile `fabricwin Whichthe tufts, i. fornied: by the Warpgipile threads,-are firmly secured in the backino, and present a smooth surface to the fabric inthe nished piece.

A further object is to provide a fabric of the character stated, in which the'tufts areforined by Warp `pile threads in banks of sin, each bank divided `into `two series of three pile threads, With all three of .cachee ries of threads extending. in the Asaine direction, and crossing and opposite to, the direction of the three pile threads ofthe `other series in the sani@ bank.

A further object is to improve upon the fabricdisclosed in `Patent No.` 1,169,835,

granted to us Februarylth, 191e.`

lWith these and other objects infview the invention consists in certainnovel features of construction and combinations and arrangernetsof parts as will be. inorefully hereinafter described andpointed out in the claims.

Alln` the accoinpanjying1 drawings Figure l is an exaggerated view-` in longitndinal section, illustrating our :improved pile fabric.

Figs. 2, 3, d, 5, 6, and 7 are-vieWs similar to Fig. l on a somewhat reduced scale, each view showing; butone `thread connecting the backing fabrics, and i F ig. d is a `dia,g'rainniatie plan View of the fabric Xafter the pile is cut.

hi and Y represent the top andibottoin backing1 fabrics which are eonneotedbjv Warp pile threads l, 2, 3, and 1?, 2a, and sirespectively. All of these threads constitute a single bank idividedinto two seriesiof` three threads each. The threads l, 2, and 3 represent the odd reed dents in Weaving and drop frein the top fabric to the bottom in succession, one pick or fillingathread apart, and then from the bottom fabric they extend to thetop fabric in succession one pick apart..

We would have it understood that We mean by the term .series of three threads, to re fer to a fgroup of three pile threads, which are successively Vplaced 4transrersely tof the fabric andere separated, or `set olf frein the other threads by axbiridiing` avarp thread.

llhefpilethreads la, 2U, and 3a represent the even reed dents, and Work just the opposite freni :the odd;` ones, or iirstseries as above explained.

. 'llhe top` backing fabric` consists-ofibinfh ing ararp threads, 6,. and @and weft threads A, B, il), Il), and F.. woven between the binding warp threads G and?.

.The slower backing' fabricu Y binding' Warp tliireads dand 5 threads rh,wl3j, C', D', Ff therein.

"llheupper aiidfloaver `picks of the'wveft threads are siniultaneously` Woven by the shuttlesiand hcncerforiconvenience of de`` scriptioir, these pairs of picks loflthe weft threadsiare given corresponding letters,ithe reference letters of the picks ofthe bottoniv fabric bein@ primed as described.

`ildhile Fig. l ilhistrates twobinding Warp threads in. bothiupper and `ion/er backing` fabrics, it isrtoi be `understood that `but a .single bindingvg` Warp3 thread is located between: each series of three Warp pile threads, asindicated niostelearlyi lin Figs; 2, 3, d, 5, G1, and 8 .respc-:ctii'fely..V

oDescribing `each of thervarp pile threads of the bank of sin, 2 illustrates `the location of thread l. flhislthread l passes over thread fr, under thread B; over thread C, thence `down to and underlthread D', thence over thread l andunder threadF.

The" thread l@ is `shownclearly in `Fig 3, where it Will be noted that this thread passes under threadl A', over thread E', under thread C", thence up to and over thread` D, under ithread l, ahd over thread F.

VIn Fig. if' it will be noted that thread 2 pzzzssesi under thread El., over `thread B, thence down to and under thread D',

consists of with weft and F Woven thence under thread E, thence np `to and over `tl'iread F.

Thread 2a is shown in Fig. 5 as passing over thread A', under thread B', up to and over thread C, under thread D, over thread E, and then down `to and under thread F.

Fig'. 6 shows thread 3 as passingI over thread A, thence down to and under thread thread Cg thence over B thence over thread C under thread D', thence up to and over thread E, and thence under thread F.

Fig. 7 shows thread 3a passing under thread A, thence up to and over thread B, under thread C, over thread D, thence down te and under thread E', and thence over thread F.

By comparing Figs. 2 3, 4 5, 6 7, it will be noted that the threads 1, 2 and 3 are disposed directly opposite to the threads la, 2a, and 3a.

In weaving, the warp threads of one series indicated by l, 2, and 3, all extend parallel to each other and in the same direction as shown in Fig. l, while the other series of threads, la, 2a and 3a extend in parallelism, but in the opposite direction crossing the threads l, 2 and 3.

lVhen the fabric is cut on a middle line between the two backing fabrics, the surface shown by Vthe ends of the tufts will be smooth and even, and all the tufts will be firmly secured in their backing fabric.

Various slight changes might be made in the general form and arrangement of parts described without departing from our invention, and hence we do not limit ourselves to the precise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having fully described our invention what we claim as new and desire to secure by Letters Patent is:

l. A pile fabric, comprising top and bottom backing fabrics, a bank of pile threads connecting the backing fabrics, each bank consisting of two series of three threads each, the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread, the threads of each series all extending in the same direction and crossing the three threads of the opposite series which extend in the opposite direction.

2. A pile fabric, comprising top and bottom backing fabrics, a bank of pile threads connecting the backing fabrics, each bank consisting of two series of three threads each, the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread, the corresponding threads of each series eppositely disposed, the threads of each series extending in parallelism in the same direction and in a. di-

rection opposite to the threads of the other` series, the threads of one series crossing the other at a point midway between the backing fabrics.

3. A pile fabric, comprising top and bottom backing fabrics, a bank of pile threads connecting the backingfabrics, each bank consisting of two series of three threads each, the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread, the threads of each series all extending in the same direction and crossing the three threads of the opposite series which extend in the opposite direction, each backing fabric consisting of weft threads and binding warp threads, a filling shot or weft thread of each backingl fabric located between each pair of pile threads, and in parallelism one above the other, the said pile threads in both top and bottom fabrics woven with three of said shots, and a single binding warp thread in each backing fabric between each series of three pile threads.

t. A pile fabric, comprising top and bottom backing fabrics, a bank of pile threads connecting the backing fabrics, cach bank consisting of two series of three threads each, the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread, the corresponding threads of each series oppositely disposed, the threads of each series extending in parallelism in the same direction and'in a direction opposite to the threads of the other series, the threads of one series crossing the other at a point midway between the backing fabrics, each backingfabric consisting of weft threads and binding warp threads, a filling shot or weft thread of each backing fabric located between each pair of pile threads, and in parallelism one above the other, the said pile threads in both top and bottom fabrics woven with three of said shots, and a single binding warp thread in each backing fabric between each series of three pile threads.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
